Not sure if a breeder or just a special duck

http://lancaster.craigslist.org/grd/5260219403.html but this person is keeping 4 boys, 8 girls, and 3 babies in a kiddie pool together, letting them breed whenever they want? I don't see any hay in there, only one place to hide, this is obviously in a basement... This is how people adopt a pregnant female, this is how guineas get diseases. Too cramped, plus "3 unknown sex 4 month old.." ????
correction: 2 kiddie pools, no hides.
